To all whom, it may concern.-

Be it known that 1, CHARLES W. MoMAsruns, a citiaen of the United States, residing at Elwood, 1n the county of Madison and State of Indiana, have invented a new and useful Improvement in Gate-Operating Devices, of which the following is a specification.

This invention is an improved construction of gate-operating device, the object being to provide an exceedingly cheap and simple device which can be easily operated by the approach of a vehicle in either direction.

Another object of the invention is to so construct the operating rods and levers that all of the parts will be held in a locked position when not inoperation.

\Vith these various objects in view the invention consists in the novel features of construction and combination of parts hereinafter fully described, and pointed out in the claims.

In the drawings forming a part of this specification, Figure l is a perspective view showing the practical application of my invention. Fig. 2 is a sectional elevation. Fig. 3 is a detail section on the line 3 3 of Fig. 2. Fig. i is a PGISPGCblW-B view showing the upper portion of the hinge. Fig. 5 is a perspective View showing the lower portion thereof. Fig. 6 is an enlarged plan view of the joint between the operating-rods. Fig. 7 is a detail sectional view on the line 7 7 of Fig. 6.

Referring to the drawings, A indicates the post to which the hinges are connected, and B the batten of the gate, to which the hinges are also connected.

C C indicate the collars rigidly fastened to the post A, each collar having an outwardlyprojecting flange C, the upper face of which is grooved, as shown at C and adapted to receive the antifriction-balls D.

Collars E E are fitted loosely upon the post A, each collar being provided with a flange E, grooved as shown at E, said collars E being arranged above the collar 0, so that the balls D will be held between the grooved flanges of the two collars. The collars E are connected to the gate by means of arms F, provided with parallel ears or plates G, which are bolted to the end batten of the gate, as most clearly shown. Pull-rods H are pivotally connected to the lower collar E at diametrically opposite points, each point of attachment being ninety degrees from the arm F. The opposite end of each pull-rod is connected to a cranked tripping-lever I, the end of the rod being formed with a transverse sleeve H, in which the end of the trippinglever works, said lever being provided with a lug l, which works in a cam-groove H produced in the sleeve H, and by means of which the rod H is shifted laterally as the lever I is tripped when a wheel strikes the same when approaching the gate, the purpose of the said lateral shift of the end of the thrustrod H being to throw the line of thrust ob liquely instead of in a straight line with the center of the post, thereby causing the lower collar to be turned, and consequently the gate. A rod K has a bifurcated end K, which fits upon the end of the crank tripping-lever and embraces the sleeve H at the end of the rod H, as most clearly shown in Fig. (5. The opposite end of each rod K is connected to a cranked trippinglever L, which normally rests in a position at right angles to the position of the adjacent cranked lever I. It will thus be seen by reference to Fig. i. that both levers L are down and both lovers 1 are up, and a vehicle in approaching the gate from either direction will strike the lever l and operate the rod H and open the gate, the lever ll being depressed during the said operation and the lever L moved to an upright position. As the vehicle passes through the gate it first passes over the otherlever l, which is in a low ered position. and then contacts with the other lever L, which is in a raised position, and forcing said lever down serves to raise the other lever l, and consequently close the gate. The sleeve H. is also provided with shoulders H to limit the up-and-down movement of the said sleeve with reference to the bifurcated end of the rod K, said shoulders contacting with said end and acting stops and holding the rods practically locked in their raised and lowered positions.

It will thus be seen that I provide an exceed ingly simple construction of gate-operating means which will el'iiciently carry out all of the objects hereinbefore mentioned.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the post and gate, of the fixed collars arranged upon the post, the movable collars connected to the gate and movable upon the fixed collars, rods connected to the lower movable collar at diametrically opposite points and provided with sleeves at their outer ends, said sleeves having internal cam-grooves, the cranked tripping levers,

each provided with a lug engaging the carnrically opposite points, the opposite ends of groove in the sleeve, the pull-rods having a said rods being provided With grooved sleeves, bifurcated end through which the end of the the cranked tripping-levers provided with 5 crank tripping-lever passes and a second set lugs engaging the grooves in said sleeve, the 5 of cranked tripping-levers connected to the pull-rods connected to the said tripping-levers outer ends of the pull-rods as set forth. and first-mentioned rods, and a second set of 2.
